| In this thesis, I present a novel, replicated multi-wavelength electro-optic measurement system. In the proposed system, multiple laser sources at different wavelengths go through an electro-optic modulator at the same time to measure a single electrical pulse. The primary aim is to increase the number of temporal measurement points beyond what can be achieved by conventional methods. Since the SNR is substantially reduced by the EO modulator, a pulse replicator is added into the system to recover this ratio. The SNR is improved by averaging the train of replicated pulses. In addition to increasing the SNR of the signal, the optical replicator enhances the high-frequency response of the detected optical pulse beyond what can be achieved in a single measurement. This system is suitable for the extraction of single shot, high-bandwidth signal from environments with high levels of electro-magnetic interference (EMI) and ionizing radiation, which requires that the detection apparatus be far from the measurement point. |
